Dental Term Definitions

A

Abscess - Acute or chronic, localized inflammation associated with tissue destruction. 

Abutment - Tooth or root that retains or supports a bridge, fixed or removable prosthesis.

Air Abrasion - A device that uses tiny particles of aluminum oxide blasted in a stream of air at the tooth to remove the decayed debris and ruined enamel of cavities. This procedure usually eliminates the need for anesthesia, though it is not usable for all procedures where a drill has normally been used.

Amalgam - An alloy used in direct dental restorations.

Anesthesia - Drugs and procedures that relieve the sensation of pain. Various types include general anesthesia, IV sedation, needle-less anesthesia and local anesthesia.

Apicoectomy - Surgery to the root section of the tooth through the side of the gums where the root is severed at the base of the tooth and then the tooth is filled. Usually this is done when a root canal has failed to eliminate pain or infection, and is usually performed by an endodontist.

Attrition - The normal wearing down of the surface of a tooth from chewing.

Autoclave - A device that has a chamber where instruments are placed and steam under pressure is injected in order to complete sterilization. OSHA (Occupational Safety & Health Administration) standards require all dental offices have sterilization procedures for instruments that include the use of an autoclave.
